Application filed August 3, 1889 -Serial No. 819,668. (No model.)

taching buttons; and it has for its object to construct a machine ofthis class-in which the buttons shall be automatically fed from areceptacle or hopper into a 'slotted tube, by meansof which they shallbe con veyed to and held in the desired position while wire is beingthreaded through the eye of each successive button, by which the wireshall be severed andformed into staples, and by which the said staplesshall be driven through the material or fabric to which the buttons areto be attached and clinched.

The invention consists in the improved construction, arrangement, andcombination of parts, which will be hereinafter fully described, andparticularly pointed out in the claims.

In the drawings hereto annexed, Figure 1 is a perspective view of myimproved machine for attaching buttons. Fig. 2 is aside view of theopposite side of the same.

Figs. 13 and 11 are detail views of the bench and anvil.

Like numerals of reference indicate like parts in all the figures.

The base of my improved button-attaching machine consists of a tubularstandard 1, mounted upon suitable legs or supports 2 2, and having atits upper end a horizontal annular flange 3, which is perforated toreceive Fig. 5 is abolts 4, by means of which the machine may beattachedto the base.

5 designates a rod or plunger arranged to move vertically in the tubularstandard and operated by means of a foot-lever or treadle 6, by means ofwhich the said rod or plunger may be moved in a downward direction bythe pressure of the foot of the operator. The plunger 5 is retracted orforced in an upward direction by the action of a coiled spring 7,suitably arranged within the tubular casing or standard.

8 designates a casing provided at its lower end with-a flange 9, bymeans of which it is attached to the flange 3 at the upper end of thestandard 1. The casing S is provided with an angular bearing for avertically-sliding rod 10, the lower end of which is suit-ably connectedwith the upper end of the vertically-sliding rod 5 in the standard 1.The vertically-sliding rod 10 is provided at its upper end with across-head 11, carrying parts of the operating mechanism which will behereinafter more fully described.

12 designates a bracket, which is bolted or otherwise suitably securedto the casing S and which extends from the same in a rearward direction,and is provided with a bearing for a transverse shaft 13, carrying thefeed-wheel lat and an annularly-grooved cylindrical roller 15, whichconstitutes one of the wire-feeding rollers. The bearing of the shaft 13has an upwardly-extending bracket 16, atli'ording a bearing for atransverse shaft 17, upon which an additional Wire-feeding roller 13 ismounted. The shafts 13 and 17 are furthermore provided with spur wheelsor pinions 1.), meshing together and serving to transmit motion from theshaft 13 to the shaft 17, thus causing the wire-feedingrollers 15 and 18to be operated' simultaneously,when the feed-wheel 11 of the machine isin operation. A spool'20, holding the wire, may be mounted upon asuitable bracket in any desired position which shall enable the wire topass conveniently between the feed-rollers.

The button-feeding wheel, which has been designated by 14, is composedof an annular disk of brass or other suitable material, one of the sidesor faces of which is provided with an annular peripheral flange 21,having notches ing tube at the proper time.

22, to receive the ends of a series of horse shoe-magnets 23, which aresuitably attached in any convenient manner to the face of the disk let.A bracket 24, forming an extension of the bracket 12, carries asuitablyconstructed hopper 25, the bottom of which is provided with aslot 20, to admit the rim of the disk 14, with its flange 21. It will beseen that when the wheel or disk 14 is rotated the magnets 23 willsuccessivcl y pass through the slot 26 and finally escape at the upperor front end of the hopper.

To the upper front end of the hopper, and registering with the slot 26,is suit-ably attached one end of the button-feeding tube 27. Said tube,which may be constructed of suitable metal, is provided with a slot28,extending through its entire length. The upper or rear of the saidslot registers with the front end of the slot 26 in the hopper E35, andthe said slot, which has a slight spiral twist, terminates on one sideof the said tube, as will be clearly seen in Fig. 4 of the drawings.

The bracket 12 is provided with aforwardlyextending portion 29, whichconstitutes what I term the bench of the machine; or this bench portionmaybe independently attached to the casing S. Extending longitudinallythrough the bench 29 is a shaft 30, the front or outer end of which isprovided with an upwardly-extending bent or curved arm 31.

The bench 29 is provided with a vertical opening or recess 32 toaccommodate the plunger, which will be hereinafterdescribed, and therear end of said opening or recess is diagonal, as will be seen at Therear wall of the opening 32 is pierced for the passage of a knife orcutter 3i, which extends rearwardly and is provided with a longitudinalgroove or opening 35, serving as a wire-guide. The knife or cutter isretained in position by means of a set-screw 36, extending through theside of the bench 29. This enables the said cutter to be con venienllydetached whenever desired for the purpose of sharpening the same. Theside of the vertical opening 32 is open, as shown, at 37, and in thesaid opening is secured the lower front end of the button-feeding tube27, the slot 28 of which terminates adjacent to the said opening Thelower end of the buttoirfeedingtnbe has an inwardly-exten ding spring38, which serves to hold in position the button which is to be attached,the said spring permitting the said 1 button to be readily removed fromthe feed- The bench 29 has in its upper side a transverse groove orrecess 39, which communicates with the opeir ing 32, and which affordsaccommodation for an arm 40, extending from the shaft 30 at an angle tothe arm 31 at the front end of said The said arm 40, which forms the imandrel over which the staple is bent, is pro 1 shaft.

vided at its outer end with a notch 41, to enable the eye of the buttonto pass, as will be hereinafter explained.

42 designates the anvil, which may be made vertically adjustable bymeans of a screwthreaded support 43, by means of which it is secured tothe iiange 9 of the casing 8. The top of the anvil has a head 44:,provided with a longitudinal notch 45, which is shaped in such a manneras to receive the ends of the staple and to turn and clinch them. In theconstruction of this device, however, no novelty is herein claimed.

The cross-head 11 of the vertically-reciprocating rod 10 is provided atone end with a pawl 40, adapted to engage a ratchet-wheel 47, which ismounted upon the shaft 13 of the button-feeding wheel 14. It will thusbe seen that when the rod 10 is vertically reciprocated an intermittentrotary motion will be imparted to the said button-feeding wheel. Thismotion does not take place with any absolute regularity, and for reasonswhich will be presently set forth it is not necessary that such shouldbe the case. The front end of the cross-head 11 carries the plunger 48,which works vertically upon the stem or shank 50,

and which when in a raised position abuts against the shoulder 5& at theupper end-of the stem or shank 50. The sliding portion or plunger 53 isadapted to move vertically in the opening 32 in the bench 29 of themachine, the rear side of said plunger being diagonal to correspond withthe diagonal rear side 33 of the said opening. The sliding portion orplunger 53 has in its lower side a longitudinal groove 55, for theaccommodation of the piece of wire from which the staple is to beformed, and the said sliding plunger is also provided with a transverseopen ing or recess 50, adapted to fit over the arm or mandrel 40, overwhich the staple is to be bent, the front and rear walls of said recessbeing vertically grooved, as shown at 57. The upper end of the recess 56has an upwardly-cxtending notch 58, registering with the notch 52 in thestem 50, for the accommodation of the eye of the button which is to beoperated upon. The movement in an upward direction of the slidingplunger 53 is limited by the shoulder 54, as above stated. To limit themovement of the said plunger in a downward direction and to prevent itfrom sliding off the stem 50, it is provided with a pin 5!), extendingtransversely through a slot 60, which is formed vertically in the stem50. The vertically-sliding plunger 53 is provided at its upper edge, onone side, with the hinged arm-(l1, adapted to it against theside of theplunger 48, which latter is provided with a block or projection (52,against which the upper end of the hinged arm 61 may abut when thesliding plungcr5 5 is at the lower end of its vertical movement. Thehinged arm 61 is provided with a laterally-extending cam (33, adapted toengage a corresponding cam 64: on the bench 29, and which serves, whenthe plunger is moved in a downward direction, to engage the cam 63 andrelease the arm 61 from contact with the pro j ection 62, thuspermitting the plunger 53 to slide or move in an upward direction uponserves, when the plunger is raised, to restore the arm Glto its normalposition in contact with the block or projection 62. The front side ofthe vertically-sliding plunger 53 has at its upper end a recess 66,forming a camshaped shoulder 67.

The plunger 48 is provided with a camshaped projection 68, adapted onthe downstroke of the plunger to engage the rearwardly-bent portion 69of the arm 31, which extends radially from the front end of the shaft30, journaled longitudinally in the bench of the machine.

It will be seen that the relative positions of the arms 31 and are suchthat when the arm 31 extends in an upward position previous to thedownstroke of the "plunger the arm 40 extends laterally through thevertical opening or recess 32 in the bench 29 at a point directly belowthe wire which is being fed forward through the guide or groove 35 inthe cutter 34:. lVhen the plunger is on its downstroke, the pressure ofthe plunger against the arm 40 will rock or oscillate the shaft 30. Atthe same time the cam or projection (53 strikes the bent portion 69 ofthe arm 31, thereby guiding the said bent portion over the shoulder 67of the plunger 53. A

spring is suitably arranged to restore the shaft 30 and its arms 31 and40 to their normal position when the plunger moves in an upwarddirection.

My improved button-attaching machine is operated by means of a treadle6, which serves to impart a vertical reciprocating motion to the rod 10,carrying the cross-head 11 and its attachment. On the downward movementof the cross-head the pawl 46 engages the ratchet 47 of the shaft 13,which is thereby rotated in the direction indicated by thearrow in theseveral figures of the drawings. A supply of buttons is placed in thehopper 25, said buttons being of the ordinary kind, provided with eyesthat are formed usually of steel wire, said eye being the only metallicportion of the buttons. Such being the case, the buttons will beattracted by the horseshoe-magnets attached to the feeding-wheel, andthe eyes of the buttons will naturally be found to adjust themselvesbetween the arms of the said horseshoe-magnets. The slot 26 in thebottom of the hopper is contracted toward its wheel the buttons will beautomatically detached from the magnets, and they now drop by gravityinto the lower and discharge end of the feeding-tube. It will be seenthat the feeding-wheel is operated by each operation of the stem 50. Asuitably-arranged spring 65 deed, is this necessary. 'At the same timeitis entirely immaterial if a button should be so deposited by eachmagnet, for the reason that the operation of the machine will be in nowise affected by the number of buttons contained in the feeding-tube.When the latter is completely filled, the result will simply be that anybuttons which may adhere to the magnets will be brushed off from thelatter when the discharge end of the hopper is reached. The wire-feedingdevice, which is attached to the shaft 13 and geared from said shaft tothe shaft 17, serves to feed the wire which passes from the spool 20between the rollers 15 and 13, and from thence through the groove 35 inthe cutter 34 into the vertical opening 32 in the bench of the machine.The wire, it will be observed,is fed by friction by therollers 15 and1S,

and the latter will slip loosely upon the wire cient length of the wirehas been fed, the feed automatically ceases. This is partly due to thewire-guide in the cutter 3a, which extends in a rearward direction towithin a short distance of the discharge end of the feeding rollers, andwhich prevents any kinks from forming upon the wire. \Vhen in operationthe plunger is moved in a downward direction, the sliding plunger willfirst enter the opening 32, and the' sharp rear edge of the movableplunger 53 will engage the front edge of the cutter 34 and sever theportion of the wire whichextends through the opening 32 and abutsagainst the front wallet the said opening. The severed portion of thewire will be found to extend through the eye of the lowermost button inthe feeding-tube, the eye of which button is in alignment with thedischarge end of the wire-guide in the cutter 34. The lower edge of saideye rests in the notch ll at the outer end of the arm 40, which extendstransversely through the opening 32, and which serves to support thesevered portion of the wire from which the staple is to be formed. Thegroove 55 in the under side of the plunger 53 will now engage the endsof the severed portion of the wire and force them downwardly on oppositesides of the arm 40, thus shaping the staple, the ends of the wire beingaccommodated in the grooves 57 in the front and rear walls of the recess56 in the under side of the plunger. As the plunger descends, the bentportion 69 of the arm 3t bears against the side of said plunger, thuspreventing the arm .0 from being thrown out of its approximatelyhorizontal position While the staple is being formed. hen the staple hasbeen formed, the bent portion 60 of arm 31 is engaged by the cam orprojection 68 and forced laterally through the recess 66 and over theshoulder 67 of the plunger, thus permitting the arm 40 to descend and bethrown out of the way under the pressure of said plunger. During thetime occupied by the preceding operations the plunger 53 has beenretained in a lowered position upon the stem 50 bythe arm 61 engagingthe block or projection 02 extending laterally from the plunger i8. The

cam 63 of the arm 61 now engages the cam (ll upon the bench 29, therebythrowing the arm 61. out of engagement with the projection .(32 andpermitting the stem 50 to descend within the plunger 53. The notch orrecess 51 at the lower end of said stem will thus engage and pressagainst the upper end of the staple, the arms of which will thus bedriven through the material to which the button is to be attached, andwhich is rested in the proper position upon the face of the anvil. Thearms of the staple, having been forced through the material, will engagethe recess 45 in the face of the anvil, whereby they will be turnedinwardly toward each other and clinched by the continued downwardpressure of the plunger. When the plunger recedes in an upwarddirection, the spring 70 serves to rest-ore the shaft 30, with itsattachments, to its original position, and the arm 61 is likewise, bythe action of the spring 65, restored to engagement with the block orprojection 2, and the plunger, as soon as raised, will thus be ready fora repetition of the operation. Owing to the diagonal rear wall of theopening and the corresponding diagonal shape of the rear side of theplunger 53, the ends of the wire forming the staples will be cut otfdiagonally, and thus be provided with pointed ends, which will easilypenetrate the material to which the buttons are to be attached.

The advantages of my improved machine for attaching buttons will bereadily appreciated by those familiar with this class of machines.

The construction is simple and of such a nature asnot to be liable toget out of order, and the operation offorming the staples and attachingthe buttons will be performed with neatness, accuracy, and dispatch.
